How is six and five hundredths written in expanded notation and numerals

Usimov [2.4K]

Answer:

In Expanded notation it is $6\times 1 + 5\times \frac{1}{100}$

In numerals it is 6.05

Step-by-step explanation:

Expanded notation

Expanded notation is a helpful way to rewrite numbers in order to show the place value of each digit.

Normal number of we have

.........,Hundred, Tens ,Unit

eg. 1.) 514

5 = hundred place

1 = tens place

4= unit place

Now for decimal numbers

tenths,hundredths,thousandths........

eg. 1.) 0.25

0 = unit place

2 = tenths place $\frac{1}{10}$

5 = hundredths place $\frac{1}{100}$

We will have example in numerals and it expanded notation.

6.05 ( six and five hundredths)

Expanded form

$6\times 1 + 5\times \frac{1}{100}$

Here,

6 is in Unit place

0 is in Tenths place

5 is in Hundredths place

Please solve this question.

Aleks [24]

Answer: see proof below

<u>Step-by-step explanation:</u>

$x^a=y^b=z^c\ =k\\$

Then $x^a=k\qquad \rightarrow \qquad x=k^{\frac{1}{a}}$

and $y^b=k\qquad \rightarrow \qquad y=k^{\frac{1}{b}}$

and $z^c=k\qquad \rightarrow \qquad z=k^{\frac{1}{c}}$

y³ = x · z

$(k^{\frac{1}{b}})^3=k^{\frac{1}{a}}\cdot k^{\frac{1}{c}}\\\\k^\frac{3}{b}}=k^{\frac{1}{a}+\frac{1}{c}}\\\\\\\bold{\dfrac{3}{b}=\dfrac{1}{a}+\dfrac{1}{c}}\quad \checkmark$
